Thanks. I was reading about sudo. Another approach is to type sudo -v,
then give your password which will be valid for 5 minutes, then sudo su -,
which gives you the root path, then you can type commands for 5 minutes
without typing sudo each time.
DSL apparently would not need the sudo -v part, would it need sudo su -?
I was going to try this but the dratted computer is back to 101 i/o rom
error and probably needs a $20 voltage board replacement.
The 0x10 error I was getting trying to boot from 2-floppy BL3 is
supposedly due to 'bad media' - so I tried another BL3 set but by then
could not boot.
The boot process stopping between the popad bug OK line and the POSIX
conformance testing line while trying to boot the parport zip boot disk,
with 386 BL3 kernel, is the same as what I was getting trying to boot with
the 486 kernel on a 486 or pentium. The 486 kernel was supposedly buggy,
but this 386 kernel worked on all my other computers for booting that
parport zip boot disk. Odd. Maybe I should try the pentium kernel here.
If we can fix the hardware boot problem, this really does seem like a good
candidate for burning BL2 and/or BL3 to a bootable CD rather than going
through all the sudos and insmods and chroots and THEN waiting several
minutes for BL3 and then mplayer to load from zip disk.
DSL seems to already set up sound. Maybe it has a movie player? Ubuntu
has some sort of movie player (which is used as a jpeg viewer) but is
ridiculously slow to load, looking for new hardware, networks, etc.
It should at least be happy with 320MB RAM.
If I ever get this figured out, maybe I could post an iso file for a
minimal BL3 with mplayer and sb16 sound. (Except that it is laptops that
seem to be missing floppy or hard drives, and in my experience they have
more obscure sound chips that might need ALSA sound). Can you make a
256MB RAMdisk for use with BL2, with a slightly modified kernel (this
one does 4MB RAMdisks) like DSL does?
